Hi all! I'm new on this forum and I started recently working on Arduino UNO board with the Ethernet Shield.In my project I use the Ethernet.h library to send data to a PC and the library SPI.h to save the same data on the SD card.With these library my project works perfectly, like I desire; but when I only add the directive#include <Wire.h>to communicate with a DS1307 Real Time Clock, then the program compiles correctly and it loads on the chip, but the program don't save data to SD or send them through ethernet.I repeat: to the working sketch I only insert the include directive, no instruction.I think this could be some kind of conflict: does anyone have had the same problem or have an idea on know how to solve it?
